Book excerpt: Due to its stable physical and chemical properties and its abundance in nature, quartz is widely employed in industrial and high-tech applications. However, the presence of diverse types and states of impurities in quartz ores from different geological formations poses a challenge in the process of purifying high-purity quartz, leading to wastage of raw materials and escalated costs. This study presents the socio-economic applications of quartz, scrutinizes the formation and separation mechanisms of impurities in quartz ores from a mineralogical perspective, examines the obstacles faced in quartz purification, explains the current state of development, and provides a technical summary of quartz purification. The analysis reveals that lattice impurity elements and various types of inclusion impurities are the principal factors affecting the purity of quartz. Various green separation techniques are applied based on the composition of the quartz minerals and the state of the impurities. Standard practices may involve physical pre-treatment such as scrubbing, ultrasonic crushing, and electromagnetic pulse cracking, followed by rough cleaning through color separation, superconducting high gradient magnetic separation, and flotation, and chemical pre-treatment (high-temperature or microwave roasting with chloride doping, and ammonium sulfate thermal crushing combined with water quenching to remove gas-liquid inclusions from quartz minerals). Finally, finishing processes such as fluorine-free and catalytic hot-pressure acid leaching or microbiological purification treatment with filamentous or Aspergillus fungi are used to obtain high-purity silica sand with an anticipated purity of about 99.99%.

Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated book offers a concise overview of the geology of Egypt in the context of the geology of the Arab Region and Northeast Africa. An introductory chapter on history of geological research in Egypt sheds much light on the stages before and after the establishment of Egyptian Geological Survey (the second oldest geological survey worldwide), Hume's book and Said's 1962, 1990 books. The book starts with the Precambrian geology of Egypt, in terms of lithostratigraphy and classifications, structural and tectonic framework, crustal evolution and metamorphic belts. A dedicated chapter discusses the Paleozoic-Mesozoic-Cenozoic tectonics and structural evolution of Egypt. A chapter highlights the Red Sea tectonics and the Gulf of Suez and Gulf of Aqaba Rifts. Subsequent chapters address the Phanerozoic geology from Paleozoic to Quaternary. The Egyptian Impact Crater(s) and Meteorites are dealt with in a separate chapter. The Earth resources in Egypt, including metallic and non-metallic ore deposits, hydrocarbon and water resources, are given much more attention throughout four chapters. The last chapter addresses the seismicity, seismotectonics and neotectonics of Egypt.

Book excerpt: Advances in Polarography, Volume 2 covers the proceedings of the Second International Congress held at Cambridge in 1959 in honor of the 70th birthday of Professor Heyrovsky. This volume is composed of 35 chapters and begins with intensive discussions on the theoretical and fundamental aspects, as well as pertinent equations in polarography. Considerable chapters are devoted to the chemical and metallurgical applications of the technique, with emphasis on the trace determination of certain compounds. The remaining chapters explore other application of specific polarographic technique, such as nicotinic acid, iso-benzpyrylium salts, and metal complex analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Mercury is a toxic global contaminant that is transported through the atmosphere, is deposited in terrestrial and aquatic ecosystems, and concentrates up the food chain, reaching levels that can harm both humans and wildlife. This book reports the latest findings describing the distribution, deposition, and measurement of this airborne pollutant as well as the human and environmental impacts of artisanal mining of mercury and gold. The research originates from around the world and highlights the importance of atmospheric mercury research and the Minamata Convention on Mercury, a global treaty to protect human health and the environment from anthropogenic emissions of mercury.
